Updating Processor Boot Code

As documented in HS02865, there are at least three strategies for updating processor
boot code firmware with subsequent methods for reloading the processors. See
HS02865 for further details.
This section combines the three Hotstuff strategies into two major methods:
•
Method 1: Using G06.24 OSM or TSM SPRs, Update Processor Boot Code Using
the Online Option on page 8-4
With this method, it is assumed that you have at least the G06.24 OSM and TSM
SPRs installed on your client and server. If this is the case, you can use the explicit
online boot code update available in either TSM or OSM. Note that if you are on an
S7000, the online update option does not appear.
It is possible that you can update your OSM and TSM SPRs to the latest versions,
and still decide, based on previous adhered-to practices, not to update the
processor millicode using the explicit online option. Follow the steps described in
Method 2.
•
Method 2: Using Your Current Pre-G06.24 OSM or TSM SPRs, Update the
Processor Boot Code and Issue a Hard Reset or Equivalent on page 8-10
With this method, it is assumed that you have down-rev G06.24 SPRs installed on
your client and server. If this is the case, you cannot use the explicit online boot
code update. It will cause a processor halt.
It is possible that you can update your OSM and TSM SPRs to the latest versions
and still decide not to update the processor millicode using the explicit online
option available in either TSM or OSM. In that case, you must issue a Hard Reset
action or a Reload. The Hard Reset or Reload action can be performed during the
system load procedure.
